[RE-wrenches] SMA Core 1 Inverter

[Kelly Larson]

Dear estemed Wrenches,

I will be inspecting a system with SMA’s new Core 1 inverters and am wondering: What experience do you have with this inverter?  

I think it is the first inverter made to sit freestanding on a commercial roof.  It looks like it has some super interesting features, including “String Failure Detection”.  (Why is this feature deactivated by default?)  

I’m not sure how well it will satisfy the rapid shutdown requirement when the roof array areas are broken up, but on one with a contiguous array area, it looks like it’ll work for the 2014 NEC.

Any bugs or issues I should know about?

Thanks in advanced for your replies!

Blessings,
Kelly
